Watch Series 7 45 mm

This A2478 Apple Watch Series 7 (GPS+Cellular, 45 mm) is the global model, sold outside North America. The Series 7 models are similar to the Series 6 but feature larger, more durable displays and faster charging. This cellular model can connect online independently but requires an iPhone 6s or later with iOS 15+. The 45 mm version has a 396x484 "Always-On Retina" LTPO OLED screen, protected by Ion-X glass (aluminum cases) or sapphire crystal (stainless steel cases), with a ceramic and sapphire crystal back. Battery life is rated for up to 18 hours. At least eleven configurations were available from resellers, combining various aluminum and stainless steel cases with different bands.

International technology reviewers consistently characterized the Apple Watch Series 7 as a meaningful evolutionary step that addressed key user complaints from previous generations. The larger 45mm display received universal acclaim for significantly improving text readability and app navigation, while the faster charging capability was praised as a game-changing improvement for daily usability. Global market analysts noted that the Series 7 represented the first time Apple had delivered substantial display improvements without compromising battery life, making it particularly appealing to international users who demanded both functionality and reliability across diverse usage patterns.
